The Linked User Model Ontology (LUMO) is a cross-domain ontology aiming to serve as the background knowledge base (KB) for knowledge-based personalisation and recommendation systems. LUMO models semantics to formally represent the contents of networked media items, in a manner pertinent to the media consumer. In addition, it models information about contextual information regarding the user/consumer, but also the content itself.
Its main purpose is to provide a holistic and uniform vocabulary and schema, that is slim enough so as to enable tractable logical inference over the KB for the personalising content delivery by the media provider, but also concise enough so as to represent efficiently the diverse aspects of the generic media super-domain.
LUMO is designed as an OWL ontology, with its expressivity restricted to the OWL 2 RL profile, in order to maintain the minimal complexity and address scalability and user privacy issues.
LUMO is currently accompanied by mappings to several existing ontologies and vocabularies, in separated OWL ontologies. Mappings were produced with the use of the LogMap (Logic-based and Scalable Ontology Matching) tool and, in most cases, revised manually.

The LUMO ontology was initially developed within the LinkedTV project (orginally named LinkedTV User Model Ontology), in order to enable semantic personalization and contextualization in the networked media domain.
It has since been extended in the premises of the Hyper360 H2020 project, to enrich it with more mid-level knowledge across various media sub-domains.

Mappings for the expanded entities were re-produced (through LogMap) and revised manually. LUMO maps to:
Significant expansion to include domain specific semanics in the areas of music events, music, art and cultural history, educational and social events, exercise, health and wellbeing, consumer goods of various sorts, tourism and travel, and several sub-areas of the former.
In version 3.0, mappings have not been extended.
Updates after use case testing in the premises of LinkedTV. Expansion of the Arts-culture-entertainment subdomain.
Mappings produced (automatically with LogMap), but not revised manually, were added for:
First model. Core hierarchy, object properties and axioms, especially w.r.t to topics and sub-topics, established.
Mappings produced (automatically with LogMap) and revised manually to:
